Incompatible with Matlab 2023b on Mac ARM

[HappySpring]

I have Matlab 2023b installed on an M1 MacBook. And I got the following error messages after trying to start MatLAB from Jupiter Lab:

env: /Applications/MATLAB_R2023b.app/bin/maci64/path_per_install: No such file or directory
mkdir: /bin/maci64: Operation not permitted

There is a folder named maca64 at /Applications/MATLAB_R2023b.app/bin/ instead of the maci64. It looks like that a new architecture maca64 is introduced in Matlab 2023b, and it is not supported by the jupyter-matlab-proxy yet.

Thank you for using jupyter-matlab-proxy, @HappySpring!

Can you please confirm that you are able to start this version of MATLAB outside of jupyter-server-proxy? I have observed this sort of error message stemming from MATLAB when there is a mismatched install. Example: An install of Intel-based MATLAB on an ARM-based machine and vice-versa.

With R2023b natively supporting Apple Silicon macOS, one can look to install respective MATLAB on a M1 Macbook by navigating to https://www.mathworks.com/downloads/web_downloads and Downloading for macOS (Apple Silicon).

Hope that helps!

Hi @krisctl,

I have checked that the matlab can be started normally outside of the jupyter-matlab-proxy. Here is some detailed information.

Hi @HappySpring

I just downloaded, installed and activated MATLAB R2023b Update 4 on my M1 Mac and was able to successfully run MATLAB through the kernel.

These are the steps I took:

Step 1: Install MATLAB

1. Download and install the Java Runtime from this link.

2. Downloaded and installed MATLAB R2023b for MACA64 from the MathWorks website.

3. Started MATLAB R2023b from on the desktop and activated it with my online licensing credentials. (Your activation step may be different based on your license type)

4. Ensured that I am able to repeatedly open it without it asking me for licensing information. This step ensures that I can use the Existing License Option when I start the MATLAB Kernel through Jupyter Lab.

5. Added the newly downloaded MATLAB onto my system path using the following command on the system terminal: sudo ln -fs sudo ln -fs /Applications/MATLAB_R2023b.app/bin/matlab /usr/local/bin/matlab

6. Verified that this change took effect using the following command on the system terminal: readlink -f `which matlab` Output:

   /Applications/MATLAB_R2023b.app/bin/matlab

Step 2: Setup Python environment

1. I use miniconda to manage my python environments.

2. Create a new python environment conda create -n r2023b python=3.10 -y

3. Activate this conda environment called r2023b conda activate r2023b

4. Install jupyter-matlab-proxy python -m pip install jupyter-matlab-proxy

5. Verify that the packages were installed: python -m pip list | grep matlab Output:

   jupyter-matlab-proxy              0.10.0
   matlab-proxy                      0.10.0

6. Activate my environment one more time, conda sometimes needs this to update the PATH after an installation. conda activate r2023b

7. Verify that the jupyter lab I'm about to launch is from this environment: which jupyter Note how the jupyter executable is from the conda environment we r2023b that we previously created

   /Users/pbk/miniconda3/envs/r2023b/bin/jupyter

8. Finally, we are ready to start Jupyter Lab: juptyer lab

9. Click on MATLAB Kernel, run a command, select Existing License and watch the magic:

10. Final result:

If I had to guess the issue on your machine might be setting the PATH as shown in Step 1. 5 sudo ln -fs sudo ln -fs /Applications/MATLAB_R2023b.app/bin/matlab /usr/local/bin/matlab

Hope this information helps!

Hi @prabhakk-mw,

Thank you for you detailed instructions.

Finally, I figured out what happened. I am able to fix the problem by installing another anaconda natively on apple silicon.

jupyter-matlab-proxy probably requires that python and Matlab should share the same architecture. For my case, both native Matlab and native python on apple silicon are required. I installed anaconda in 2021 when its native support for apple silicon had not arrived. The anaconda works normally on my Mac (at least for my research) but it is still for intel. Anaconda supports apple silicon natively about May 2022. However, it cannot update from an intel version to an apple silicon version automatically. I believe that is why the 'jupyter-matlab-proxy' is looking for 'maci': the python (included in anaconda) on my Mac is for intel platform.

Figured out what happened, I installed the latest anaconda supporting apple silicon natively, reinstalled jypyter lab and 'jupyter-matlab-proxy' in the new environment. Everything works after that.

Happy to hear you've worked it out!
